SPECIFICATION forming part of Letters Patent No. 589,688, dated September 7, 1897. Application filed May 3,1897. Serial No. 634,845. (No model.)

To aZZ whom it may concern.-

Be it known that 1, AARON Tnonas BINK- ERD, a citizen of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Carpenters Combination-Gages and I do declare the fol lowing to be a full, clear, and exact description of the invention, such as will enable othare skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in carpentersgages, and the object is to provide a tool of this class adapted to avariety of uses.

To this end the invention consists in the construction, combination, and arrangement of the device, as will be hereinafter more fully described, and particularly pointed out in the claims.

Figure 1 is an elevation of my improved gage. Fig. 2 is alongitudinal section through the same. Fig. 3 is a bottom plan view, and Fig. 4 is a transverse section through the head-block.

Like letters of reference indicate like parts throughout the several views.

Referring now to the details of the drawings by letter, A designates the gage-stock, which.

is graduated upon one or more sides, as may be desired. At one end it is provided with a ferrule a and with a cutting-disk A, the edge of which is sharpened, as shown, and which disk is rotatably mounted on a screw a, held in the end of the stock, as shown in Fig. 2. This dish serves to keep the stock from the work during the use of the gage, and thus reduces the friction to a minimum. Bein g sharpened, it also serves as a marker from either side. The opposite end of thestock is split, as shown at a and the split portions are designed to be brought together sulficiently to firmly hold between them a bit by means of a screw 13, which is held in the split portions, as shown best in Fig. 3. These bits 0 are designed to be interchangeable and are for the purpose of working beads or recdwork, especially around arches or circular work. They are formed differently at each end, so as to be used either end, one for one kind of work and the other for another kind. This end of the stock is formed with a transverse slot of, as shown in Fig. 3, for the reception of with the central longitudinal slots (0 and a,

as best seen in Fig. 2, which slots are designed to receive fins or lugs on the slides, which will now be described.

D represents one of the slides, and it is formed centrally with a fin or lug (Z, which is designed to work in the slot a to guide the slide in its movements, and one end terminates in the cross portion D, which is concaved, as shown in Fig. 3. This is designed for marking arcs or curves both concave or convex. The opposite end of this slide is provided with an outwardly-extending lip or lug d, as shown in Figs. 1 and 2, which is designed to engage a notch (Z in the end of the gage head or block E, as shown in Fig. 2, the gage head or block being form ed with a channel through or in which the slide moves. This head or block may be of any well-known form, except as herein specified, and is provided with the thumb-screw E, as shown in Figs. 1 and 2, for binding the same at any desired or adjusted position on the stock. This screw also serves to bind the slides in their adjusted positions.

Upon the opposite side of the stock there is provided an adjustable steel rod, which also serves as a fin or guide and is used in marking tenons, mortises, (be. having at each end a' point or inarkerf", and outside of this rod is a slide G, which has a longitudinal groove g, through which the rod is movable and also in the groove or slot of of the stock, as shown in Fig. 2. This slide has at one end a lug g, which is designed to enter a notch g in the head or block, as shown in Fig. 2, and at the other end it terminates in a cross portion G, which is providedwith a notch g to receive the marker or point on that end of the metallic rod F, as is also clearly shown in Fig. 2.

The manner of using the gage will be readily understood from the foregoing description when taken in connection with the accompa- ICO nying drawings. The slides and rod are independently adjustable, and it will be readily seen that by proper adjustment the thick ness, as well as the width, of any desired piece may be taken at the same time. The gage will be found especially useful in marking for butt-hinges and mortise-locks on doors, &c., Where an ordinary gage cannot conveniently be used.

Having thus fuily described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The stock A formed with the longitudinal slot (t the slide G, provided with the iongitudinal groove g, alined with said slot a the rod F provided at its outer ends with the scratch-points f f and arranged to simultaneously engage the slot a and groove g, and the adjustable block E, provided with the thumb-screw E, and adapted to simultaneously secure said stock A, slide G, and rod l: in position, substantially as shown and described.

2. The stock A formed with the longitudinal slot a the slide G, formed with the groove 9 and lug g and cross portion G, the outer face of which is provided with the notch g' in combination with the rod F, provided at its outer end with the scratch-points f f, and the block E, provided with the notch 9 substantially as shown and described.

In testimony whereof I hereunto aifix my signature in presence of two witnesses.

AARON THOMAS BINKERD.
